Pyrolysis reactions of coniferyl alcohol as a model of the primary structure formed during lignin pyrolysis was written by Kotake, Takeo;Kawamoto, Haruo;Saka, Shiro. And the article was included in Journal of Analytical and Applied Pyrolysis in 2013.Application of 3929-47-3 This article mentions the following:
It has been suggested that cinnamyl alc.-type structures are formed during lignin primary pyrolysis using model dimers. In this article, the pyrolysis reactions of trans-coniferyl alc. (CA) bearing a guaiacyl moiety were studied under N2 at temperatures in the range of 200-350 C, with particular emphasis on the evaporation/degradation processes. Some (less than 15%) of the CA evaporated without undergoing any degradation reactions, whereas large portions of the CA were converted to polymerization products together with monomers (up to ∼15% in total) with various side-chains. The cis-isomer of CA and 4-vinylguaiacol with a C2 side-chain were also identified. Methylation of the phenolic OH group of CA substantially reduced the formation of polymerization products, whereas the influence of the methylation on the side-chain-converted monomers was limited. Since the methylated CA was not effective for quinine methide formation, quinine methide and radical pathways were indicated as more important reaction mechanisms for the polymerization and side-chain-conversion processes, resp. These results suggest that CA, if it was formed through pyrolytic cleavage of lignin β-ether linkages, tended to be degraded before it could be recovered through evaporation Furthermore, the recovery of different monomers suggested the process was greatly dependent on the relative evaporation/degradation efficiencies. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Application of 3929-47-3).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Application of 3929-47-3
